AssIGNoRs or ONE-THIRD 'ro HENDERSON B. DOUGLAS, oie-NEW GLASGOW, NOVA scomIA, CANADA.

Be it known that we, SoREN HANssoN and vIsAK MoELLER, yresidents of New Glasgow,

in the Province of Nova Scotia and Dominion of Canada, have invented a new and useful Improvement in Car-Roofs, of which kthe following is a specification.

This invention relates to an improvement in car roofs, and particularly in roofs for railway cars. l l

The obj ect of the invention 1s to s1mpl1fy and improve the general construction of car roofs, and provide a roof which can be readily manufactured at low cost, which is to a certain `degree flexible and therefore better able to withstand the racking strains of service, in which the lnumber of parts is` materially reduced, and which is so arranged asto materially reduce the leakage of water, snow or the like to the, inside of the car, and which also provides drainage gutters or channels for conducting to the outside of the car any water or moisture which may find its way through the joints in the car roof. n

The invention comprises the constructlon and arrangement of parts hereinafter described and claimed.

In the drawings Figure 1) represents a partial plan view of a car roof embodying the invention, the left half showing the roof sheets removed; Fig. 2 is a longitudinal detail section, on a larger scale, taken4 on the line 2-2, Fig. 1; Fig. 3 is a detail plan view taken directly over one of the carlines, and at the side edge! of the roof; Fig. 4 is a sectional elevat1onon the line 4 4, Fig. 3; Fig. 5 is a detail s1de elevation corresponding to Figs. 3 and 14; F1g. 6 is a plan view at one cornerl of the car; Fig. 7 is a section on the line 7 7, F1g. 6; and Fig. 8 is a cross section on the line 8-8, Fig. 1.

The roof frame comprises side plates 1, which may be of any suitable section but are shown as Z-bars with their webs vertical and flanges horizontal, two or more longitudinal stringers or purlins 2, which are inverted channel members, as shown in Fig. 8, end plates 3, which are pressed plate metal members with their side and upper edges bent to form flanges, and transverse members or carlines 4. rllhe end plates 3 have their flanges riveted to the side plates 1, and to the end roof sheets, as indicated at 5 Specification of Letters Patent.

and 6, and their webs to the corner post 7, which fis also riveted' to the web ofthe side plate. The edges of the end roof sheets are bent down 'over the en'd plates 3, as shown at 7, to insure a tight joint and prevent the entrance of rain or moisture. The longitudinal stringers are connected tothe end plates by angle members andy lie `be-v neath and support the transverse carlines4, which are riveted-thereto, as indicated at 8. The carlines are somewhat arched in the usual manner and at their ends rest upon and are riveted directly to the upper flanges of the side plates 1. The carlines may be of any suitable section, but preferably are of some suitable section which` provides a gutter or channel for carrying oil3 any water, snow or moisture which may-'ind its way through the joints between the roof sheets. In the form shown in the drawings, the carlines are of modified T section, being inverted with the webs 9 and edge flanges 10 extending upwardly and forming two channels or guttersll lying on 4opposite sides of the web. The web 9 is cut down on an incline at each end .of .the carline, as'indicated at 12, the end. portion of the carline being also depressed downwardly where it f rests on and is secured to the side plate 1.

The roof` sheets, indicated at 13, are formed of platemetal with the edges of adjacent sheets overlapping at the carlines. These roof sheets intermediatev their edges lie flat uponthe longitudinal stringers 2, but are not directly secured thereto. At the sides of the car the edges of the roof sheets are bent downwardly over the side kplates 1 and are riveted thereto, as indicated at 14. At. the carlines the edges of the roof sheets are bent upwardly and rest directly upon the edges of theupwardly extending flanges 10 of the carlines, the edge of one sheet being bentupwardly on an incline, preferably to a point beyondthe 4upper edge of the flange 9 of the carline, as

duces a longitudinal extension 18 on each metal for this purpose.

consequently the roof has a` certain amount is depressed or becomes shallower at the ends of the carlines, until at the extreme edges of they roof sheets which lap down over the side plates 1, the inverted U sec-r tion is quite shallow-and forms a restricted channel, indicated at 17. This also proroof sheet at each end of the joint between adjacent roof sheets, which provides a material overlap between the roof sheets where they are secured to the side plates, without the necessity of providing extra At the saine time, the restriction of the channel 17 materially reduces the liability of snow or rain being forced into the cai' along the eaves. l Any water, moisture or snow which finds its way through the joint between roof sheets is trapped by the channels 11 and is conducted along tlie 'gutters formed thereby to the sides of the car, where it is discharged yover the side plates through the restricted channels 17, and runs down outside the car. rllhe inverted U shaped edgeI portions of the roof sheets also form supports for the running board saddles 20 which are bent metal members riveted directly to the edges of the roof sheets, as indicated at 21, and to which theusual running board 22 is secured. Preferably inner protecting plates 23 are placed underneath the inner heads of the rivet heads 21 to prevent water leaking through the riveted joint. j

vThe construction described is very simple and can be readily manufactured. The roof is also flexible so that damaging effects ofjwarping strains are reduced, if not entirely eliminated. Also, the joints between roof sheets are simple, and forni an eflicient protection against the leakage of water or moisture into the car,l and the special orin of carlines provides eflicient glitters for carrying oft any liquid which may find its way through the joint. Ait the same time, the restriction of the channels for carrying oflI the water prevents snow or rain from beating its wayinto the car at l the ends of the-joint.

What we claim is:

1. A. car roof, comprising side plates, carlines connecting the same and formed of inverted T sections each having a web and side flanges, and rootI sheets secured to the side plates, the edges of adjacent roof sheets being bent upwardly over the Webs of said carlines into inverted U shape, the bent edgeV portions of said roof sheets being shallower at the ends o f the joints between root' sheets to forinrestricted openings for the discharge of water, each roof sheet at the end of a carline having a longitudinally extending portion overlapping the next adjacent roof sheet and secured thereto.

2: A car roof, comprising side plates carlines connecting the saine and formed of inverted T sections having an upright web and side flanges forming drainage utters on opposite sides of said web, and roo sheets secured at their ends to the side plates and having their edge portions overlapping each -other and also overlapping the webs of said carlines but being free of connection thereto.

3. A car roof, compiising side plates, carlines connecting the same and formed of inverted 'l' sections having an upright webV and side flanges forming drainage gutters on opposite sides of said web, and roof sheets secured at their ends to theV side plates and having their edge portions overlapping each other and also overlapping the webs of said carlines but being free of connection thereto, said roof sheets also having portions adjacent their edges resting on the upper edges of the flanges of said carlines and supported thereby.

4a A. car roof, comprising side plates, carlines connecting the saine and formed of inverted T sections having an upright web and side flanges forming drainage gutters on opposite sides of said web, roof sheets secured at their ends to the side plates and having their edge portions overlapping each other and also overlapping the webs of said carlines but beingfree of connection thereto, and longitudinal purlins located'below `said carlines andsecured thereto, the roof sheets resting on said purlins between 'adjacent carlines.

5. A car roof, comprisingside plates, carlines connecting the same and formed of inverted T sections having an upright web and side flanges forming drainage gutters on opposite sides of said web, roof sheets secured at their ends to the'side plates and having their edge portions overlapping each other and also overlapping the webs of said carlines but being free of connection thereto, said roof sheets also having portions adjacent their edges resting on the upper edges of the flanges of said carlines and supported thereby, and longitudinal puilins located below said carlines and secured thereto, the roof sheets resting on said purlins between adjacent carlines.

In testimonywhereof, We have hereunto set our hands.
